Spectrogram to Color

September 10, 2013 | 8:16 am

I would like to know if anyone knows any objects or methods to synthesize color out of spectrograms. I would like to, for example, draw a line over a vision light spectrum and obtain color results which included saturation, brightness or possible combinations (magenta).

Thanks in advance!

Are you talking about the [swatch] object, or am I missing something in the question?

Hello,

Yes, perhaps I didn’t explain myself well enough. What I’d like to do is to obtain tangible color results out of cartesian coordinates of spectra; for example, given the following spectra

get in return the magenta color.
